Repolarization Alternans and Ventricular Arrhythmia in a Repaired Tetralogy of Fallot Animal Model
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2015 Background Ventricular arrhythmia is an important cause of late death in patients with repaired tetralogy of Fallot (rTOF). By using an rTOF canine model, we investigated the role of repolarization alternans and its electrophysiological mechanisms ...

A study of the motor unit action potential by means of computer simulation [PDF]
, 1978 In order to study the motor unit action potential a computer simulation model was developed. It is based on the superposition of single muscle fibre potentials of the fibres belonging to the motor unit.

Angle-action estimation in a general axisymmetric potential [PDF]
Mon. Not. R. Astron. Soc. 426: 128-139, 2012, 2012 The usefulness of angle-action variables in galaxy dynamics is well known, but their use is limited due to the difficulty of their calculation in realistic galaxy potentials. Here we present a method for estimating angle-action variables in a realistic Milky Way axisymmetric potential by locally fitting a St\"ackel potential over the region an orbit ...

Nerve Impulses Have Three Interdependent Functions: Communication, Modulation And Computation [PDF]
arXiv, 2021 Comprehending the nature of action potentials is fundamental to our understanding of the functioning of nervous systems in general. Here we consider their evolution and describe their functions of communication, modulation and computation within nervous systems.

Action Potentials that Go the Distance [PDF]
Neuron, 2002 Dendrodendritic inhibition between mitral and granule cells in the olfactory bulb is thought to play an important role in olfactory discrimination. In this issue of Neuron, explore the propagation of action potentials along the secondary dendrites of mitral cells and their modulation by dendrodendritic inhibition.

Transcranial Focused Ultrasound Modulates Electrical Behavior of the Neurons: Design and Implementation of a Model [PDF]
Journal of Biomedical Physics and Engineering, 2020 Background: Recently, ultrasonic neuromodulation research has been an important and interesting issue. Ultrasonic neuromodulation is possible by the use of low-intensity transcranial focused ultrasound (tFUS) to stimulate or inhibit the neural structures.
